Nitrile Gloves Chemical Resistance: A Practical Guide with Chart, Evaluation, and FAQ

Content

Nitrile gloves resist a long list of common chemicals, but they are not a universal shield. The performance gap between handling a dilute acetic acid solution and working with acetone is enormous. Your first decision should not be just choosing nitrile as a material. It should be confirming whether the specific nitrile glove in your hand has a tested breakthrough time for the exact chemical you are exposed to.

The short answer is that nitrile handles weak acids, alkalis, oils, greases, and many alcohols extremely well. It fails quickly in ketones, aromatic hydrocarbons, and chlorinated solvents. Knowing this difference prevents accidents and wasted inventory.

How Nitrile Glove Chemical Resistance Works

Nitrile is a synthetic copolymer made from butadiene and acrylonitrile. Unlike natural latex, it contains no proteins, so it causes fewer allergic reactions. The chemical resistance comes from the polymer matrix itself, which repels oil and water-based chemicals to different degrees.

Three factors determine whether a nitrile glove will protect you around a specific chemical:

Polymer composition – The acrylonitrile content varies between manufacturers. Higher acrylonitrile improves oil and solvent resistance but can reduce flexibility. A 28% acrylonitrile glove behaves differently from a 32% version in benzene exposure.
Glove thickness – A 5-mil nitrile glove may have a breakthrough time of 10 minutes for a particular solvent, while an 8-mil glove can stretch that to 35 minutes. Thickness is the easiest physical variable to inspect before purchase.
Coating or treatment – Sandy or foam nitrile finishes change the surface texture but do not fundamentally alter the base polymer. However, a double-dipped glove adds an extra barrier layer that measurably extends protection.

If you are handling a chemical mix, you must check the weakest link. Every solvent and additive in the mix matters. A glove that survives 50% sulfuric acid could fail in the same solution if it also contains 10% naphtha.

Nitrile Gloves Chemical Resistance Chart

The chart below is a general reference based on widely used industry data. It shows the relative suitability of disposable nitrile gloves for common chemical families. Actual breakthrough times depend on thickness, manufacturer formulation, and temperature.

Table 1: Typical nitrile glove compatibility for common industrial chemical groups. Ratings are advisory only; always verify with glove-specific test data.
Chemical Family	Typical Example	Resistance Level	Usage Note
Weak acids	Acetic acid (10%)	Excellent	Safe for extended tasks
Moderate acids	Sulfuric acid (50%)	Good	Timed use only
Alkalis	Sodium hydroxide (40%)	Excellent	Common in cleaning
Oils and greases	Motor oil, hydraulic fluid	Excellent	Nitrile's strength
Primary alcohols	Ethanol, methanol	Good	Short-duration tasks
Ketones	Acetone, MEK	Poor	Rapid swelling and failure
Aromatic hydrocarbons	Benzene, toluene	Poor	Very high permeation
Chlorinated solvents	Trichloroethylene	Poor	Do not rely on nitrile

One practical takeaway: if your workplace uses a mixture of toluene and acetone, your nitrile gloves are a temporary convenience, not a protective barrier. You would be far safer with a different glove material or a thicker barrier construction.

Chemicals Nitrile Gloves Resist Well

Nitrile gloves provide excellent protection for weak acids, inorganic bases, oils, greases, and many aliphatic solvents. This is why they replaced latex gloves in most industrial settings over the last decade.

Weak and moderate acids

In laboratory and manufacturing environments, nitrile gloves are routinely used against acetic acid, phosphoric acid, and low-concentration hydrochloric acid. According to a widely circulated chemical resistance reference, "generally speaking, nitrile gloves are resistant to many weak acids, including some nitric acids, phosphoric acids and hydrochloric acids" (source: gloves.com nitrile gloves chemical resistance guide). A 10% acetic acid solution with an 8-mil nitrile glove can often allow more than 8 hours of continuous contact.

Oils and greases

Nitrile's strongest application area is petroleum products. Motor oil, hydraulic oil, cutting fluids, and heavy grease do not degrade nitrile quickly. In a typical CNC machining cell, a pair of quality nitrile gloves can last an entire shift if they are not mechanically torn. The synthetic rubber absorbs only tiny amounts of oil before saturation, which is why nitrile is the default choice in automotive shops.

Alkalis

Sodium hydroxide, potassium hydroxide, and ammonium hydroxide solutions are handled safely with nitrile gloves in concentration ranges used by food processing plants and cleaning services. A 40% NaOH solution does not cause noticeable swelling in an 8-mil nitrile glove within a typical work cycle.

Alcohols

Ethanol, isopropanol, and methanol can be handled for short periods. A 70% isopropyl alcohol wipe or spray will not instantly destroy the glove, though continuous soaking for an hour may cause a whitish surface hardness. For applications like pharmaceutical compounding where alcohol is frequently used, nitrile remains a better choice than latex.

Chemicals That Break Down Nitrile Gloves

If you work with any of the following solvent families, treat your nitrile gloves as a short-lived barrier with a timer running. The chemical will cross through the glove within minutes.

Ketones

Acetone, methyl ethyl ketone, and methyl isobutyl ketone cause nitrile to swell rapidly and become rubbery. The glove visibly expands and turns gummy within 15 to 30 minutes of immersion. Even brief contact can cause skin contamination because the chemical migrates through the polymer structure quickly. Alternative materials like butyl rubber or PVA-coated gloves are preferred.

Aromatic hydrocarbons

Benzene, toluene, xylene, and styrene have high permeation rates through nitrile. The breakthrough time at room temperature can be under 10 minutes for a 5-mil glove. You may not notice visible degradation because permeation happens at the molecular level. That is why checking a chemical resistance chart is vital; visual testing alone is dangerously misleading.

Chlorinated solvents

Trichloroethylene, perchloroethylene, and methylene chloride attack nitrile more aggressively than aromatic hydrocarbons. As noted by Enviro Safety Products in their materials guide, nitrile gloves do provide some protection from chlorinated solvents such as trichloroethylene and perchloroethylene, but only in concentrated exposure scenarios with very thick gloves. In practice, the safe exposure window is just tens of minutes.

Strong oxidizing agents

High-concentration hydrogen peroxide, nitric acid, and concentrated sulfuric acid cause oxidation and degradation. A 70% nitric acid solution can make a nitrile glove brittle within a few hours. Even if the glove is not pierced, the polymer loses elasticity and cracks easily, allowing the chemical to reach your skin.

How to Evaluate Nitrile Glove Chemical Resistance

Glove manufacturers report chemical resistance using three standard metrics. The most widely recognized testing standards are ASTM F739 in North America and EN ISO 374 in Europe. Understanding these metrics helps you parse product datasheets and select a glove that actually protects your workers.

Breakthrough time

This is the most safety-critical number. It tells you how long it takes the chemical to pass through the glove material when continuous contact is maintained. For example, a breakthrough time of 30 minutes means the glove should be replaced twice within a one-hour exposure task. An 8-mil nitrile glove may have a breakthrough time of 15 minutes for acetone, whereas a 10-mil glove shows 25 minutes.

Permeation rate

This measures how quickly the chemical molecules travel through the glove material once breakthrough happens. A higher permeation rate means the chemical reaches your skin faster and in a larger quantity. It is usually given in micrograms per square centimeter per minute. Low permeation rates are often more important than long breakthrough times for very toxic chemicals.

Degradation

This is the physical change in the glove after contact. You can observe swelling, hardening, cracking, or discoloration. Degradation is reported in rating scales from 1 (no visible change) to 4 (severe physical change). Even a glove with a long breakthrough time can degrade at the surface and lose its mechanical strength, so both criteria must be considered together.

A glove rated Excellent in a resistance chart typically has a breakthrough time above 8 hours, a permeation rate below 0.1 µg/cm²/min, and no visible degradation.
A Good rating corresponds to a breakthrough time between 1 and 8 hours.
A Poor rating means the breakthrough time is under 30 minutes, and in many cases under 10 minutes, making the glove unsuitable for protection against that chemical.

Choosing the Right Nitrile Glove for Your Task

The selection process is not complicated if you follow a simple sequence. Do not skip the first step; most chemical glove failures come from skipping it.

Identify the exact chemicals and concentrations. A 10% sulfuric acid solution is very different from concentrated 98% acid. The same nitrile glove can be adequate for the first and catastrophic for the second.
Compare the glove thickness and length. For most chemical tasks, choose at least 8-mil thickness. A longer cuff provides better splash protection and keeps the seal tighter around your wrist.
Check the manufacturer's resistance chart. If the chart confirms a breakthrough time of at least 60 minutes for your chemical, the glove is likely acceptable for routine work. For emergency or high-risk exposure, aim for a minimum of 8 hours of breakthrough time.
Test on the job with a short pilot period. Let a small group of workers use the gloves for one shift. Look for visible swelling, stiffness, or odor with work gloves before making a bulk order.

Nitrile-coated work gloves offer a different profile from disposable nitrile gloves. They combine a knitted liner with a nitrile coating on the palm or full surface. This design is ideal for assembly, packaging, and material handling tasks where oil and grease are present, but where the worker also needs grip and dexterity rather than chemical splash protection.

A 13-gauge polyester liner with nitrile coating is a common choice for maintenance crews and warehouse workers. It provides abrasion resistance and enough flexibility that workers can handle small parts without removing the glove. Similarly, a 13-gauge nylon liner with nitrile coating offers a slightly smoother touch for more precise tasks. If your work involves both oil exposure and a risk of cuts, a thicker nitrile-coated cut-resistant glove may be the safer route.

For wet or humid environments where workers sweat through their gloves, a bamboo or polyester ribbed liner with nitrile coating breathes better while still offering oil resistance. Consider your workload conditions, not just the gloved surface.

If the chemical risk is only incidental splash and the main hazard is abrasion, a nitrile-coated glove is an excellent fit. If the task involves direct immersion in ketones or solvents, nothing short of a specialized barrier glove will do.

Frequently Asked Questions

Are nitrile gloves acid resistant?

Nitrile gloves resist many weak and moderate acids, including acetic acid, phosphoric acid, and low-concentration hydrochloric acid. Their performance around concentrated nitric acid or hot sulfuric acid is much weaker. Always confirm the acid concentration and temperature before selecting a glove.

Will acetone dissolve nitrile gloves?

No, acetone will not completely dissolve the glove, but it causes rapid swelling and penetration. The breakthrough time for acetone can be as short as a few minutes. The glove loses structural integrity and allows the solvent to reach your skin.

How long can I wear nitrile gloves around chemicals?

There is no single time limit. It depends entirely on the chemical, glove thickness, and temperature. The safe approach is to read the breakthrough time from the manufacturer's chart and replace the gloves at half that time, or earlier if you notice swelling, hardening, or any change in texture.

Are nitrile gloves resistant to oil and grease?

Yes, this is the main strength of nitrile. Motor oil, hydraulic fluids, cooking oils, and most industrial lubricants are handled safely for extended periods. Nitrile is the preferred glove material in automotive, machining, and food manufacturing environments because of this oil resistance.

What thickness of nitrile gloves is suitable for chemical handling?

For chemical splash protection, a minimum of 8 mil is recommended. Thicker gloves such as 12 mil or 15 mil provide longer breakthrough times but reduce dexterity. Test the gloves at your specific workstation to find a balance between protection and usability. A 5-mil disposable glove is acceptable only for light, low-risk tasks.

Can I use the same nitrile gloves for every chemical in my workplace?

No. Chemicals behave differently even within the same family. A glove that works for ethanol may fail in minutes with acetone. The safest practice is to build a chemical inventory and match it against the performance data of each glove type you are considering.
